The shaft 13 is a cylindrical body having a diameter of about 30 m, and is located at a position separated from the road tunnel 10 by a predetermined length in order to communicate with the road tunnel 10 through the connecting tunnel 12 in the underground. Using the technology, the road tunnel 10 is constructed vertically from the ground to a predetermined depth. An entrance / exit opening 17 is provided on the side surface of the lower end of the vertical shaft 13 near the road tunnel 10, and a connecting tunnel 12 is connected to the entrance / exit opening 17 to communicate with the road tunnel 10. The vertical shaft does not necessarily have to be provided in the vicinity of the road tunnel 10, but can be provided in a place that is easy to locate in consideration of the extension of the communication tunnel. In addition, the central space of the vertical shaft 13 can be used as a ventilation tower of a road tunnel, an evacuation path for emergency stairs, a maintenance space, etc., so that a reasonable road tunnel can be planned. In addition, the vertical shaft, when building the road tunnel 10,
It can be used as a starting and reaching space for a tunnel machine.

As shown in FIG. 2, the turntable 14 is composed of a donut-shaped flat plate whose outer circumference is substantially the same as the inner circumferential shape of the vertical shaft 13. While making it movable on the end face,
The inner peripheral surface thereof has a gear groove 41, which engages with a rotating gear 19 attached to the rotating motor 18 to rotate the rotating motor 1.
The power of 8 causes the shaft 13 to rotate on the lower end surface.

The small cylinder 15 is made of a steel pipe, a concrete pipe, or the like, and stands vertically on the turntable 14. Further, since the small cylinders 15 are fixed in an upright state, the small cylinders 1 continuously arranged in a circle are further provided on the turntable 14.

Therefore, the rotation of the turntable 14 is prevented. The inner cylinder 20 and the outer cylinder 21 do not necessarily have to be cylindrical as long as they can hold the small cylinder 15.

The vehicle capsule 1 is placed in the small cylinder 15.
6 is arranged so that it can be raised and lowered. As the raising and lowering means for raising and lowering the vehicle capsule 16, pressurized air as a fluid sealed below the vehicle capsule 16 is used. That is, by discharging the sealed pressure air, the vehicle capsule 16 is lowered, and by feeding the pressure air below the vehicle capsule 16, the vehicle capsule 16 is raised, and the amount of air to be discharged or fed is adjusted. By doing so, the speed and stopping of the vehicle capsule 16 can be easily controlled. Further, as shown in FIG. 4, the lower ends of the pair of small cylinders 15 that face each other are connected by a communication pipe 28, and the pressure air discharged when one vehicle capsule 16 descends is circulated below the other vehicle capsule 16. Then, the pair of vehicle capsules 1 are raised by the so-called siphon method.
By linking 6 with each other, it is possible to make an economical system by effectively using the pressure air while supplementing the minimum necessary pressure air. A check valve 29 and a pressure air tank 30 are provided in the communication pipe 28 that connects the lower ends of the two small tubes.
And an air compressor 31 communicating with the pressure air tank 30 is attached to supplement the pressure air for raising the vehicle capsule 16 from the pressure air tank 30, and the check valve 29 ensures that the pressure inside the pressure air tank 30 is When the discharge pressure becomes higher than the discharge pressure due to the descent of the vehicle capsule 16, the reverse operation of the pressure air is prevented. An air valve 32 is attached to the upper end of each small cylinder 15 to allow air to be supplied to and discharged from an upper space of the vehicle capsule 16 as the vehicle capsule 16 moves up and down. By forcibly feeding pressurized air from the vehicle capsule 1
The lifting and lowering of 6 can be assisted. The communication pipe 28 is arranged in the turntable 14 and is connected to the pressure air tank 3
0 and the air compressor 31 are mounted on the turntable 14.

The vehicle capsule 16 has a circular portion that is inscribed in the circular small cylinder 15 to seal the compressed air below the vehicle capsule 16. That is, for example, it is configured as an all-cylinder type shown in FIG. 5A or a Hachimaki cylinder type consisting of the upper and lower capsule frames 33 and the capsule body 34 shown in FIG. And, in the vehicle capsule 16,
Two hermetically sealed doors 35 are attached to the outer peripheral surface so as to face each other in the front and rear in the figure, and a vehicle is moved in and out from here.
Further, an air supply / exhaust hole 36 is provided in the ceiling portion of the vehicle capsule 16 so that the air valve 3 can be moved as the vehicle capsule 16 moves up and down.
The fresh air sent to the upper side of the vehicle capsule 16 via 2 is taken in, and the dirty air due to the exhaust of the engine when the vehicle enters and leaves the vehicle capsule 16 is discharged for ventilation.

Then, as shown in FIG. 6, an upper damper 37 and a lower damper 38 are provided at the upper and lower ends of the small cylinder 15.
Is provided. The dampers 37, 38 apply the conventional technique used as a train stopper at a railway station. For example, the dampers 37, 38 are actuated by hydraulic pressure and absorb the shock when the vehicle capsule 16 moving up and down stops. And a device for adjusting the height between the vehicle capsule 16 and the ground or the road surface of the connecting tunnel 12. Further, the air sealed below the vehicle capsule 16 causes a volume change due to the weight of the vehicle capsule 16 and an impact when the vehicle capsule 16 is stopped. Therefore, when adjusting the height of the vehicle capsule 16 with respect to the road surface,
The position of becomes unstable. Therefore, in order to prevent this, an electromagnet is attached to the dampers 37 and 38, and the vehicle capsule 16 is fixed to this, so that the height adjustment to the road surface is facilitated. The positioning of the vehicle capsule 16 and the road surface can be automatically adjusted by an infrared sensor or the like. Further, as shown in FIG. 7, if a capsule stopper 39 projecting inward by a hydraulic jack or the like is provided inside the small cylinder 15 at a predetermined position on the ground or below the road surface of the connecting tunnel 12, the vehicle capsule is provided above this. The position of the vehicle 16 on the road surface can be easily adjusted by placing the vehicle 16, and the capsule can be prevented from dropping when the vehicle enters or leaves the vehicle capsule 16.

As the means for raising and lowering the vehicle capsule 16, in addition to the above-mentioned pressurized air, a normal elevator 43 shown in FIG. 8A is used, and a thread is cut on the inner surface of the small cylinder 15 shown in FIG. 8B. A gear motor 45 attached to the groove 44 and the vehicle capsule 16 or a linear motor may be used. Further, when the vehicle capsule 16 is moved up and down by such a method, the shape of the vehicle capsule does not necessarily have to be a circular shape inscribed in the small cylinder 15, and these means are used for the vehicle capsule 16 in the small cylinder 15. Do not necessarily have to be paired in the opposing position to raise one and lower the other, but the inside of the small cylinder 15 can be raised and lowered separately.

Further, since the vehicle exits to the ground or the communication tunnel 12 in the forward state, it is necessary to reverse the direction when the vehicle enters the vehicle capsule 16, so that the vehicle is inverted before and after the access structure 11. It is conceivable to provide a turntable or the like for the vehicle. However, if the vehicle is turned upside down while the vehicle capsule 16 is being raised or lowered by the turning means described later, quick access to the road tunnel becomes possible, and
It is safe because the vehicle is always moved in and out of the vehicle capsule 16 in a forward state. That is, as shown in FIG. 9A, the rotating means of FIG. 9 has a spiral groove 46, which turns 180 ° when viewed in a plane, on the inner surface of the small cylinder 15 from the height above the ground to the height of the communication tunnel 12. In addition to being provided, a protrusion 47 that engages with the spiral groove 46 is attached to the outer peripheral surface of the vehicle capsule 16, and when the vehicle capsule 16 is moved up and down, the vehicle capsule 16 is automatically moved without requiring special rotation power. The vehicle is turned 180 degrees to turn it over, and a vehicle that has entered through one of the two closed doors 35 facing each other in the front and rear direction can leave the other closed door 35 in the forward state as it is. As shown in FIG. 10, if the vehicle capsule 16 is rotatably divided into a lower floor slab portion 48 and an upper floor slab portion 49, and the protrusion 47 is provided only on the lower floor slab portion 48, Only the plate portion 48 rotates so as to face the closed door 35 when the vehicle enters the vehicle. Therefore, it is not necessary to dispose the closed doors 35 at two locations. Further, the rotating means of FIG. 11 is an elliptic cylinder 51 having a twist of 180 ° when the inner space of the small cylinder 15 is seen in a plan view, and the vehicle capsule 1
6 is configured to have a shape that matches the cross section of the elliptic cylinder, and this is automatically set as the vehicle capsule 16 moves up and down.
It is rotated by 80 °. Further, the rotating means of FIG.
Is provided and is rotated by the motor 52 to reverse the vehicle 53.

The vehicle capsule 16 has the following structure in order to ensure the safety of the vehicle when the vehicle capsule 16 is moved in and out and when the vehicle capsule 16 is lifted and lowered. That is, the vehicle is guided and fixed by providing a tire groove on the floor surface of the capsule and stoppers that are attached to the tire groove so as to project therefrom and that are positioned in front of and behind the vehicle to be housed.
Further, a door mirror is provided on the inner surface of the opposed hermetic door 35 so that the driver can perceive the relative position between the capsule wall and the car, and further an infrared sensor is provided at a predetermined position to detect the position of the invading vehicle, Check that the driver is in the correct position by the lamp or buzzer installed inside.

That is, the vehicle that has entered the vehicle capsule 16 in the forward state from the introduction path 73 on the ground after the turntable 14 turns 180 ° due to the rotation of the turntable 14 and the rotation of the vehicle capsule 16 in the small cylinder 15. When viewed in a plan view, it reaches the communication tunnel 55 at a position opposite to the vertical shaft 13 and opens the closed door 35 to exit from the access opening 17 to the communication tunnel 55 in a forward state. Then, four pairs of small cylinders 15 are erected on the turntable 14, and therefore, the rotation of the turntable 14 is stopped every 45 ° and the vehicle is stored in the vehicle capsule 16 of each small cylinder 15, whereby the turntable 14 is turned. 8 per rotation of table 14
It is possible to continuously and efficiently access one vehicle to the tunnel 54. The pair of small cylinders 15 ascend and descend in conjunction with each other as described above. Also, the rotation of the turntable 14 and the raising and lowering of the vehicle capsule 16 can be controlled in relation to each other by a computer. For example, after the vehicle is stored, the turntable 14 is moved to the vehicle capsule 16 of the next small cylinder 15 and the vehicle is moved. If the vehicle capsule 16 is controlled to move up and down all at once while the vehicle capsule 16 is being rotated to store the vehicle, or while the vehicle is being stopped to store the next vehicle, the vertical descent is not stopped each time the turntable 14 is stopped. In the configuration in which the discomfort given to the driver can be alleviated and the vehicle is turned over by the turntable 50 in the small cylinder 14, the turntable 14 is rotated, the vehicle capsule 16 is moved up and down, and the vehicle is turned over. By carrying out individually while related to each other, discomfort during movement can be further alleviated. In addition,
Since driving is not required during the movement of such a vehicle, there is no danger of a traffic accident, and during this time, the driver can take a rest by resting the driving, moderate lighting in the vehicle capsule 16, sound facilities, etc. If the relaxation equipment is installed, it is possible to promote recovery from fatigue of the driver and contribute to safe driving after leaving the warehouse.

FIG. 14 shows a case in which vehicles enter and leave the tunnel 54 for up lines or the tunnel 56 for down lines at the same time. That is, 57 and O for IN provided on the ground

It is installed so that it can be connected to the cell 16 at the same time, and in the basement, it faces the IN introduction passage 57 and the OUT introduction passage 58, and has an OUT communication tunnel 59 and an IN communication ton.
A flannel 60 is provided. Then, in the capsules 1 to 4 in the figure, the vehicle capsule 16 is rotated while rotating the turntable 14.
Down, and only the turntable 14 is rotated in the capsules 4-5 and the capsules 8-1.
8 to 8, the vehicle capsule 16 is raised while rotating the turntable 14, and the vehicle I
N and OUT are performed simultaneously.

FIG. 15 shows a case where a vehicle is accessed in a continuous road tunnel 61 in which an up line dedicated tunnel 54 and a down line dedicated tunnel 56 are vertically arranged. That is, in the small cylinder 15, two vehicle capsules 16 are vertically arranged in series at a predetermined interval corresponding to the interval between the upper and lower tunnels 54 and 56 and the connecting tunnels 62 and 63, and they are simultaneously moved up and down. The upper and lower tunnels 54 and 56 are simultaneously connected. Further, on the ground, upper and lower two-stage introduction paths 69 and 70 having a height difference corresponding to the interval between the vehicle capsules 16 are provided, thereby enabling quick entry and exit of each vehicle capsule 16. The capsule connecting member 64 is used to connect the vehicle capsules 16 in series. Capsule connecting material 6
As shown in FIG. 16, 4 is fixed to a cushioning member 68 including a cylindrical member 71 and a spring 65 housed therein, a cylinder 72 protruding from the upper and lower ends thereof, and an upper surface or a lower surface of the vehicle capsule 16. And a support rod 67 rotatably connected to the cylinder 72 by a connecting pin 66. Here, since the cushioning material 68 softens the impact between the upper and lower vehicle capsules 16 and the cylinder 72 and the support rod 67 are rotatably connected, the spiral of the inner surface of the small cylinder 15 is raised and lowered when the vehicle capsule 16 is moved up and down. Even if the rotation amounts of the upper and lower vehicle capsules 16 are different, the groove 46 can absorb the different rotation amounts.

FIG. 17 shows two adjacent small cylinders 15.
The case where the vehicle capsule 16 in the inside is moved as a unit to cope with a larger traffic volume is shown. That is, the introduction paths 57 and 58 for IN and OUT on the ground
And the connecting tunnels 59 and 60 for OUT and IN are two-lane roads that connect to the adjacent small tube 15 that is integrated with each other. In the capsules 5 to 8, only the turntable 14 is rotated, and in the capsules 5 to 8, the vehicle capsule 16 is raised to simultaneously access the vehicles in the two vehicle capsules 16.

As shown in FIG. 18, if two vehicles are accommodated in the vehicle capsule 16, the number of movable vehicles can be increased. Here, FIG. 18 shows an arrangement in which four pairs of small cylinders 15 are arranged in a shaft having a diameter of about 30 m to use a vehicle capsule having a diameter of about 7.3 m capable of accommodating two vehicles. Further, in FIG. 19, a vehicle capsule having a diameter of about 6.0 m that accommodates one vehicle is used in a shaft having a diameter of about 30 m, and the small cylinders 15 are densely arranged so as to be in contact with each other to form six pairs of small cylinders 15. The number of vehicles that can be moved per turntable is increased by standing upright. Further, as shown in FIG. 20, the number of movable vehicles can be increased also by dividing one vehicle capsule 16 into upper and lower parts and accommodating the vehicles in each.

According to a trial calculation, in the vertical shaft having a diameter of about 30 m, with respect to the access structure in which the small cylinders are arranged as shown in FIG. 21, the door is opened, the vehicle is stored, the door is closed, and the door is closed.
From 0 ° rotational movement to positioning, that is, positioning to 6
It takes about 16 seconds from 0 ° rotation movement-door opening-vehicle exit-door closing, so about 3225 / hour from 3600 ÷ 16 and about 5400 vehicles / day from 225x24. You can enter and leave. Further, if the vehicle capsule 16 that accommodates two vehicles is used, approximately 10800 vehicles can enter and leave each day.

In the above embodiment, the structure for access to the road tunnel has been described, but in addition to this, the present invention is not limited to the road tunnel, and a water level adjusting groove gas pipe / water supply for preventing lateral overflow of subways and rivers. It also includes a multipurpose groove for passing various cables such as pipes and electric wires, and an access structure to underground structures used for tunnels for superconductivity.
